Patent abstract
Provided is a CMOS operational amplifier circuit that can operate with low noise, with low current consumption, and with stability. A cascode bias voltage of a folded cascode circuit in the CMOS operational amplifier circuit is modulated by a current at an input differential stage, thereby enabling operation with low noise, with low current consumption, and with stability.
